Potting Compound Problems – Trouble with bubbles ?

Author: Saul Edwards

September 24, 2021

A common problem associated with the production of polyurethane potting compounds is the formation of carbon dioxide bubbles within the polymer. These bubbles look unsightly, and they also lower the mechanical strength of the compound, leading to component failure, due to moisture ingress.

To solve this problem, manufacturers of PU potting compounds typically use a Zeolite Powder such as 3A SUPERSIV, to absorb any water that may be present in the MDI, Polyol or filler components. Once this water has been dealt-with, the remaining raw materials will react with each other, to form a bubble-free potting compound.

For those manufacturers who do not have the processing machinery required for the dispersion of fine powders into liquids, there is an alternative product which they can use called 3A SUPERSIV Paste. This is a pre-blended liquid, that manufacturers can just pour-in to their formulation. It’s simple to handle, and it mixes into polymers with great ease.

I purchased Barrier Foil Bags from Ricardo at Baltimore Innovations and highly recommend the products and service that was provided. Samples were provided promptly, and Ricardo sourced both off the shelf and customized barrier foil bags that suited my needs. I also purchased a bag sealer and all of the products are of the highest quality. Baltimore Innovations are a reliable business partner a great source for products. I look forward to working with them in the future.
